CPU: CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.

Processor Speed: The speed at which your computer runs programs or completes tasks is determined in great measure by your computers processor speed. Processor speed is measured in gigahertz (GHz). The higher this measurement, the faster the processor. It is hard to say the speed you should look for because these chips are constantly getting smaller and contain more and more power. However, when you shop, know that the higher numbers give the best performance and factor that into your decision depending on your needs.

Storage: Whereas memory refers to the location of short-term data, storage is the component of your smartphone that allows you to store and access data on a long-term basis. Usually, storage comes in the form of a solid-state drive or a hard drive. Storage allows you to access and store your applications, operating system and files for an indefinite period of time.

RAM: RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.

Screen Karbonn Alfa A91 Champ
Screen Size: The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners. It is also sometimes called the physical image size to distinguish it from the logical image size,which describes a screens display resolution and is measured in pixels.

Resolution: Image resolution can be measured in various ways. Basically, resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtenant. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line.

Features:
WiFi WiFi is a technology that uses radio waves to provide network connectivity. A WiFi connection is established using a wireless adapter to create hotspots - areas in the vicinity of a wireless router that are connected to the network and allow users to access internet services. Once configured, WiFi provides wireless connectivity to your devices by emitting frequencies between 2.4GHz - 5GHz, based on the amount of data on the network.
Hotspot/TetheringTethering is when you turn you smartphone into a mobile Wi-Fi hotspot and share your phones 3G/4G data connection. Once you turned tethering on, any device with a wireless connection can connect to the internet via your smartphones connection.
BluetoothBluetooth is a low-power wireless connectivity technology used to stream audio, transfer data and broadcast information between devices. There are two flavors of Bluetooth technology, Basic Rate/Enhanced Data Rate (BR/EDR) and Low Energy (LE).
